My boy baby is 6 months 15 days old I think 4 times only rolling over after that 2 times he is trying to crawl is it OK for that or any other issues ? Please let me know

A. Any time between the age of 3 to 9 months so there is no problem and when you talk about crawling that usually happens between the time of 9 to 10 months in this age usually move onto their tummy so your child is doing it that is good enough as per the age of your child
